R7 240 can't display 60Hz @ 4K resolution only 30Hz

Have installed the latest drivers for the R7 200 series and can only get 30Hz using 3840x2160 resolution through HDMI 2.0 port. (Monitor supports 3840x2160 @ 60Hz.) No Display Port on my particular R7 240 card from Yeston.

 

Do I need a special HDMI cable or is there something wrong with my graphics card?

FYI: Have a second display 1920x1080 @ 60Hz running fine through DVI cable.
